For cold weather, crops should pay attention to the application of grass ash or decomposed finely divided organic fertilizer to increase the ground temperature. Facility agriculture should increase the cover of straw curtains and quilts in time to prevent freezing, prevent low temperature from invading greenhouse crops. During the cooling period, according to the weather conditions, the curtains should be properly delayed in the morning, and the curtains should be covered in advance in the afternoon to prevent the loss caused by low temperature. Existing greenhouses or greenhouses are reinforced, and membranes and laminating strips are repaired in time to prevent damage to greenhouses or greenhouses due to windy weather.
